UNT SARAH: Though matronly Aunt Sarah is a pushover for cats, she just won't give a dog an even break. When she takes over the household to baby-sit in Jim Dear and Darling's absence, she shunts Lady from the nursery. When the baby cries from the biddy's over-attentiveness, Lady gets the blame. Soon after, the coddled Siamese cats secretly demolish the living room and again she figures it to be that dog's fault. Not unlike a cat, she is obstinate, self-centered, and set in her ways. Indeed, her answer to the "Lady problem" is to have her muzzled. But like so many narrow-minded types, her own misconceptions finally become her undoing. For the muzzling touches off a course of events that leaves the baby unprotected when the home will need Lady the most. Besides Aunt Sarah, veteran actress Verna Felton also voiced a variety of other famous characters: the matriarch elephant in "Dumbo" (1941), the Fairy Godmother in "Cinderella" (1950), the Queen of Hearts in "Alice in Wonderland" (1951), Flora in "Sleeping Beauty" (1959), and Winifred in "The Jungle Book" (1967). Voice Artist: Verna Felton SI AND AM: Twin Siamese cats, Si and Am prowl in harmony, wreaking havoc all around them. Cunning and spiteful, they display the worst traits of their species. When Aunt Sarah arrives in Lady's peaceful home to baby-sit the newborn, Si and Am pop out of her basket to slink by Lady, singing a warning of sorts: "We are Siamese if you please. We are Siamese if you don't please. Now we looking over our new domicile. If we like, we stay for maybe quite a while." As they vandalize the place, terrorizing the pet goldfish and canary, Lady is helpless to stop the chaos. As they proceed upstairs to steal the baby's milk, Lady takes the offensive, barring their way with a fearsome growl. But, too devious for the innocent Lady, they end up framing her for all of their destruction. As much their "patsy" as Lady herself, Aunt Sarah carries them off exclaiming, "Oh, that wicked animal -- attacking my poor innocent little angels." Only heard singing, Si and Am were both voiced by famous singer/songwriter Peggy Lee, singing her own harmonies with herself. Ms. Lee not only wrote all the film's songs with Sonny Burke, but also voiced and performed the songs for the characters of Peg (the former star of the Dog and Pony Follies) and Darling (Lady's owner).
